SHELBY HICKS, OF PROVIDENCE, KENTUCKY, ASSIGNOR OF ONE-HALF TO JOHN W.GIVENS, OF SAME PLACE.

MECHANICAL MOTOR.

SPECIFICATION forming part of Letters Patent No. 480,724, dated August16, 1892.

Application filed April 28, 1892.

To all whom it may concern:

Be it known that I, SHELBY HICKS, a citizen of the United States ofAmerica, residing at Providence, in the county of Webster and State ofKentucky, have invented certain new and useful Improvements inMechanical Motors, of which the following is a specification, referencebeing had therein to the accompanying drawings.

Myinvention relates to a mechanical motor well adapted for operating achurn-dasher, a fly-fan, and many other mechanisms.

The invention will first be described in connection with theaccompanying drawings, and then pointed out in the claims.

Figure 1 of the drawings is a side elevation of one form of my inventionapplied as a churn-motor. Fig. 2 is a plan view of the same. Fig. 3 is aside elevation of a modified form of my invention applied as a fly-fanmotor. Fig. 4is a perspective detail view of the star-wheel on thestar-wheel shaft in engagement with the spiral flange on theoperatingshaft.

Similar letters and figures of reference indicate corresponding parts inall the views.

Referring to Figs. 1 and 2 of the drawings, A represents the frameworkof the motor, secured at its rear end to two uprights B, rising from abench C, on which the churn D is to be placed.

E is a star-wheel, comprising a hub 1 and a series of arms 2, fixed on ahorizontal shaft F, journaled in the sides of the frame A. In the outerbifurcated end of each arm 2 is journaled an anti-friction roller 3,whose treadsurface is preferably on an imaginary direct line through thelongitudinal center of the arm. By thus locating the anti-frictionrollers the torsional strain incidentally produced when they are locatedat one side of the center of the arms is avoided. Shaft F also carries abalance-wheel G and a pinion H.

I is a vertical operating-shat t loosely mounted in extensions 4 and 5of the frame A and supported therein by a collar 2', fixed on its upperend, carrying anti-friction rollers 6, which bear on the extension 4.,said rollers being mounted on pintles 7, fixed in the periphery of thecollar. On the lower end of this shaft is a coupling 0, in which issecured Serial No. 431,007- (No model.)

the stem of the churn-dasher D. For the purpose of gearing thisoperating-shaft with the star-wheel it is provided with a spiral flangeI, whose vertical length is about equal to the distance between two ofthe anti-friction rollers carried by said wheel, so that as one of therollers is about leaving the flange another one will be brought intoengagement with it, as seen in Figs. 1 and 4, whereby the force exertedby one of these rollers is not counteracted by the other, andconsequently a steady rotation is impart-ed to the shaft. Furthermore,that portion of the shaft which bears the flange is curved to correspondwith the inclination of the flange, as shown, where by while the arms ofthe star-wheel move in the arc of a circle the rollers carried therebywill, during the time of their contact with the flange, be always at thesame distance from the center of the shaft, thus having leverage andexerting power in turning the shaft throughout their travel over theflange.

The star-wheel shaft F is operated by a large gear-wheel J in mesh withthe pinion H, said gear-wheel being loosely mounted on a horizontaldriving-shaft K, j ournaled in frame A, and carrying, also, a fixedratchet-wheel L, adjacent to wheel J, one end of said shaft beingextended through and beyond the frame and squared, as at 8, for thereception of a wrench. A spring-actuated pawl M, pivoted to wheel J andin engagement with the ratchet-wheel L, serves to lock the gear-wheel toits shaft during the backward revolution of the latter.

N represents a weight having a longitudinal groove 9 in each side, and10 represents an inwardly-extending plate secured to the rear side ofeach of the uprightsB and entering the grooves in the weight to serve asways on which the weight may slide.

0 is a pulley mounted in the bifurcated upper end of a swivel P, thelatter being supported on the upper end of a rod Q, passing throughkeepers 11, secured to crosspieces b, uniting the uprights B, said rodbeing adj ustably held by a thumb-screw 12, passed through one of thekeepers.

R is a cord passed over the pulley O, and secured at one end to thedriving-shaft K and at its other end to the weight.

Any suitable governor may be used-as, for

instance, an adjustable friction-brake bearing on the driving-shaft. I

Instead of using the weight and cord to drive shaft K, I may dispensewith them and substitute a coiled spring S, secured at one end to theshaft and at the other to the frame A, as seen in Fig. 3.

In Fig. 3 I have shown the motor arranged to dr1ve a fly-fan T. In sucha use as this the frame A 1s so constructed as to rest on any sultablebase and the operatingshaft is extended upward, the anti-frictionrollers 6, carrled by the collar 1;, resting on the lower extension 5 offrame A.

The operation of my motor is so obvious as to render descriptionunnecessary.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l, In a mechanical motor, the combination, with the frame, of astar-Wheel bearing an anti-friction roller on each arm, a shaftrevolubly mounted in the frame and carrying the star-wheel, anoperating-shaft at a right angle to the star-Wheel shaft, saidoperating-shaft having a spiral flange with which the antifrictionrollers engage and a curvature corresponding with the inclination of theflange, and means for driving the star-wheel shaft.

2. In a mechanical motor, the combination, with the frame, of astar-wheel each arm of which carries at its outer end an anti-frictionroller in line with its longitudinal center, a shaft revolubly mountedthe frame and carrying the star-wheel, an operating-shaft mounted in theframe at right angles to the star-wheel shaft, said operating-shafthaving a spiral flange with which the anti-friction rollers successivelyengage and a curvature corresponding with the inclination of saidflange, and mechanism for driving the starwheel shaft.

3. In a'mechanical motor, the combination, with the frame, of astar-wheel each arm of which carries at its outer end an anti-frictionroller in line with its longitudinal center, a shaft revolubly mountedin the frame and carrying the star-wheel, an operating-shaft mounted inthe frame at a right angle to the star-wheel shaft, said operating-shafthaving a spiral flange with which the anti-friction rollers successivelyengage, and a curvature corresponding with the inclination of saidflange, a collar fixed on the operating-shaft and carrying anti-frictionrollers which bear on the frame, and mechanism for driving thestar-wheel shaft. 1

4. A mechanical motor comprising frame A, driving-shaft K, ratchet-wheelL, fixed on said shaft, gear-wheel J, loose on said shaft and carryingspring-actuated pawl M, means for actuating said shaft, star-wheel shaftF,starwheel E, carried by said shaft F, pinion II, and balance-wheel G,saidstar-wheel being provided with anti-friction rollers 3,operating-shaft I,having spiral flange I and a curve corresponding tothe inclination of the flanges, and collar 11, fixed on shaft I andcarrying anti-friction rollers 6, all constructed and arrangedsubstantially as described.

In testimony whereof I atfix my signature in presence of two witnesses.

SHELBY HICKS.
